Abstract A GaAs/GaAsSb/GaAs structure was grown on (100), (111)A, (111)B and (110) GaAs substrates by intermittent injection of AsH3, TEGa, and TMSb. The maximum Sb composition was GaAs0.79Sb0.21 on (100) GaAs. From the SIMS, PL and XRD measurements, the abruptness of the quantum well interface and lattice strain were…
To improve the luminescence properties of ZnS : Cu, a multi-doped method was used to prepare Zn(Cu(0.01) Cd(0.02) Mg(0.02))S in this paper. As a new designed semiconductor compound, particular properties of Zn(Cu(0.01) Cd(0.02) Mg(0.02))S were investigated, especially luminescence intensity and lifetime. Structure and…
Catalytic wet oxidation of simulated olive oil wastewaters has been investigated in batch and trickle-bed reactors. The comparison between two operating reactor systems is presented querying the effect of temperature and pressure. The higher decontamination rates of organic matter were obtained in the batch reactor, w…
The structure of Tl(2)Mo(9)Se(11), dithallium nona-molybdenum undeca-selenide, is isotypic with Tl(2)Mo(9)S(11) [Potel et al. (1980 ▶). Acta Cryst. B36, 1319-1322]. The structural set-up is characterized by a mixture of Mo(6)Se(i) (8)Se(a) (6) and Mo(12)Se(i) (14)Se(a) (6) cluster units in a 1:1 ratio. Both components…

Feuer frei: Die Umwandlung von coadsorbiertem CO und O2 in CO2 gelang auf einer Cu(111)-Oberfläche unter Bestrahlung mit 40 fs langen 400-nm-Laserpulsen. „Heiße“ Adatome aus der O2-Dissoziation sorgen dafür, dass das gebildete CO2 aus dem Reaktionsbereich heraus auf eine unbesetzte Stufe katapultiert wird (siehe Bild)…
The structural and vibrational properties of the MgO-supported gold clusters, Au N ( N = 25−41), have been investigated by using the first-principles calculations. It is found that they indeed prefer the open pyramidal hollow (OPH) cages in this size range, showing distinctly different vibrational spectra from other a…
In this study, through the macromolecule reaction, poly(vinyl alcohol) (PVA) was modified by quaternary ammonium cationic monomer (QAC) and the cationic PVA (C-PVA) was synthesized successfully. The structure of C-PVA was characterized by Fourier-transform infrared and Kjeldahl nitrogen content measurement. The proper…
Knife is the most commonly used single weapon in the UK and studies reveal that majority of the knife-inflicted wounds were slash type that could be disfiguring or life threatening. Currently available stab-resistant armours do not protect the arms, neck, and face as they are rigid to be worn comfortably for everyday…
Abstract Transient femtosecond absorption spectroscopy and time‐correlating single photon counting (TCSPC) photoluminescence (PL) were employed to study InS nanowires (NWs) grown by chemical vapor deposition (CVD) and determine the relaxation mechanisms in these nanostructures. Intensity dependent measurements reveale…
In the title thio-cyanate-coordinated aza-macrocyclic copper(II) complex, [Cu(NCS)(2)(C(24)H(38)N(6))], the Cu(II) atom is coordinated by the four secondary N atoms of the aza-macrocyclic ligand and by the two N atoms of the thio-cyanate ions in a tetra-gonally distorted octa-hedral geometry. The average equatorial Cu…
The title complex, [Ni(C(12)H(11)N(2)O(2))(2)(C(3)H(7)NO)(2)], lies on on an inversion center. The Ni(II) ion is coordinated in a slightly distorted octa-hedral coordination enviroment by four O atoms from two bis-chelating 4-acety-3-methyl-1-phenyl-1H-pyrazol-5-olate ligands in the equatorial plane and two O atoms fr…
In the mononuclear title compound, [Co(C(8)H(7)O(3))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)]·2H(2)O, the Co(II) ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 4-meth-oxy-benzoate anion, one nicotinamide (NA) ligand and one coordinated and one uncoordinated water mol-ecule. All l…
Abstract The presence of arsenic (As) in water is of great public concern. Arsenic exists in three common valence states viz., As(0) metalloid arsenic, As(III) (arsenite) and As(V) (arsenate). Arsenite [As(III)] is the most toxic form among arsenicals which, predominates in anaerobic conditions, generally in flooded s…
ABSTRACT Hydrogen sulfide gas is harmful to human health and causes corrosion of electronic devices, when it is present in indoor air. Porous clay heterostructures (PCHs) provide a new type of material for catalysis, adsorptive separations and as H2S sensors because their large pores allow access to their active inter…
A novel poly (vinyl chloride) (PVC) membrane electrode sensitive to benzoate ions was developed. In this electrode, N,N′-bis(salicylidene)-1,2-diaminoethane zinc(II) (Zn(SDE)) complex served as the neutral carrier and o-nitrophenylocthyl ether (o-NPOE) as the plasticizer. We investigated the influences of the neutral…

In the title compound, C(17)H(13)ClN(2)O(2)·H(2)O, the dihedral angle between the quinoline ring system and the benzene ring is 13.0 (1)°. An intra-molecular N-H⋯O hydrogen bond may influence the mol-ecular conformation. In the crystal structure, acetamide mol-ecules are linked to water mol-ecules via inter-molecular…
The influence of Li+ , Na+ , K+ , Rb+ , Cs+ , Mg2+, Ca2+, Sr2+, Ba2+, Ag+ , Cd2+, Co2+, Fe2+, Hg2+ , Mn2+, Pb2+, Zn2+ and Fe3+ on the spectroscopic properties of two dansyl (1- dimethylaminonaphthalene-5-sulfonyl) groups linked to the lower rims of a series of three, structurally related, di-ionized calix[4]arenes is…
Larkin-Ovchinnikov (LO) states typically have a singlet gap that vanishes along real-space lines. These real-space nodes lead to Andreev midgap states which can serve as a signature of LO pairing. We show that at these nodes, an odd-parity, spin-triplet component is always induced, leading to a nodeless LO phase. We f…
